## Proposed changes
Issue Number: close #xxx
there's a caller used `getPartitionExprs` and modified the result. the
result is a reference to a part of metadata. If when we create the
table, the number of editlog didn't reach the limit to generate image
file, when it reaches, the image will get the wrong metadata of
`partitionExprs` from memory which was modified.
currently we don't know why, but this root cause has been confirmed by:
```java
private void analyzerPartitionExpr(Analyzer analyzer, PartitionInfo partitionInfo) throws AnalysisException {
ArrayList<Expr> exprs = partitionInfo.getPartitionExprs();
for (Expr e : exprs) {
LOG.info("beforeB: {}", e.toSql());
e.analyze(analyzer);
LOG.info("afterB: {}", e.toSql());
}
}
```
```log
2024-06-18 21:49:07,449 INFO (mysql-nio-pool-154|695) [OlapScanNode.analyzerPartitionExpr():1561] beforeB: date_trunc(Carding_Day, 'MONTH')
2024-06-18 21:49:07,449 INFO (mysql-nio-pool-154|695) [OlapScanNode.analyzerPartitionExpr():1563] afterB: date_trunc(`a`.null, 'MONTH')
